IMPROVEMENT IN HOISTING APPARATUS.

Specification forming part of Letters Patent No. 124,380, dated March 5,187:2.

Specification describing an Apparatus for Hoisting and stowing away hayor long feed, invented by SAMUEL K. PADEN, of Pulaski, in the county ofLawrence, and State of Pennsylvania.

The invention will first be fully described, and then clearly pointedout in the claims.

Figure l is a side elevation of my hoisting mechanism, showing thecarriage locked, but the pulley unlocked. Fig. 2 is avertical,longitudinal, and sectional elevation of the same, showing the carriagetransferred and standing over the hay-mow.

A represents the supporting and track bar of the apparatus. Thisconsists of a light fiat wooden strip, a, provided with atransverselycurved strap of iron, a on each side. These iron straps arethreaded at each end, and confined to the wood by clamps a a and nuts a.They subserve two purposes, since they not only constitute the trackover which the carriage travels, but also re-enforcements to the flatstrip of wood. In consequence of this construction I am enabled toemploy a very light, portable, and easily-handled bar, which is,however, possessed of great strength. B is the carriage, which consistsof two plates, 1) b. held together by bolts b ,'and provided withfriction-pulleys b 1) b 0 is the liftingpulley, arranged centrallybetween the plates 1), and near the bottom of carriage. It has bothflanges 0 c inwardly curved and ratcheted on their peripheries, whilethe center is encircled by a rubber ring, 0, to create friction on thelifting-rope. D is a double pawl, pivoted above the pulley, and servingas a detent sufficient play is allowed to the carriage to enable it tomove freely and without retardation from closeness of parts. On adownward projection of clamp a is pivoted a loclcbolt,

E, shouldered at e, and provided with the downward and inclined andbifurcated extension 0. F is a pendent loop, which regulates the maximumdownward fall of the pawl, and b a rectangular cross-bar between theplates 1) I), over which the shoulder e catches. a is a loop on thedownward projection of clamppiece a The mode of operation is as follows:The rope to which the fork is attached extends up to the left oflifting-pulley, between it and the bolt b It then passes around and oversaid pulley to the right, when it is extended to and through loop a andto the horse, windlass, or other power used for operating it. Let thecarriage be locked and the lifting-pulley be unlocked, as shown in Fig.1 of drawing, and the weight of the fork will unwind the rope and let itdown upon the hay. This draft-rope is provided with a knot near thefork, which strikes the prongs of extension 6, lifts the bolt E, andunlocks the carriage. The latter is at once actuated by the power tomove up the inclinedtrack and supportingbar A; but, as soon as it leavesthe bolt E, the pawl at once locks the lifting-pulley C. The carriagebeing transferred to that part of the mow intended, the lifting-pulleyis held by the horse and the pawl from rotating in either directionuntil the load is emptied. This be ing done, the horse is returned, andthe carriage, by its own gravity, moves down the inclined bar A. Thesquare cross-bar b now strikes the end incline of bolt E, lifts it andthe double pawl, and then allows the shoulder 0 to fall over itand lockthe carriage.

Thus it will be perceived that this locking device, for both carriageand pulley, is entirely automatic, is effected with absolute certainty,and operates with great facility.

Having thus described all that is necessary to a full understanding ofmy invention, what I esteem to be new, and desire to secure by LettersPatent, is
